Definitions

  • a manual transmission When driving a vehicle having a manual transmission, the driver must coordinate the operation of the clutch pedal, the gearshift lever and the accelerator pedal to achieve a smooth and efficient shift from one gear to the next.
  • the structure of a manual transmission is simple and robust and provides good fuel economy by having a direct power connection from the engine to the final drive wheels of the vehicle. Additionally, since the operator is given complete control over the timing of the shifts, the operator is able to dynamically adjust the shifting process so that the vehicle can be driven most efficiently.
  • One disadvantage of the manual transmission is that there is an interruption in the drive connection during gear shifting. This results in losses in efficiency.
  • the third gear 86 meshes with the output shaft gear 90.
  • the fifth gear 88 meshes with the output shaft gear 92.
  • the odd gear ratios of the gears on the first input shaft 64 increase in a forward direction.
  • the gear 118 is connected with a ring gear 132. Ring gear 132 is in mesh with planet gears 134 (only one gear 134 shown).
  • the planet gears 134 are mounted on a carrier 136.
  • the carrier 136 has fixably connected thereto a drum 138.
  • the first input shaft forward portion splined end 68 mounts a torsionally fixed synchronizer 140.
  • a band brake 142 or a clutch (not shown) is provided to selectively ground the carrier 136 via the drum 138.
